CoreSymbolication (which produces symbolicated crash traces) does not yet support the version 4 header. It would be great if we could have a separate option to control the version of the line table independently from the debug info version. We are in the process of making DWARF 4 the default on Darwin and being able to upgrade the debug info independently from the line table independently would make staging this a lot easier.
